To f1.1/ whom.: ifV mffty/ concern:

,lle it known thet l', THOMAS W'. GREEN, e. citizen oil the United Stuten, residing in Philadelphie. in the eountv oi Philadelphia i und State of Pennsylvania, have invented l certain new end useful Improven'iento in Packing for RotaryT Blo\\ 'ei'-S|loiite, oi which the Vi'ollowingr a speoi'ieation.

My invention relates to the peel-:ing lor shafts oiy rotor)Y blowers that are needr for pumping zur, `as and similar fluide and the oi `lect oi my improvement is to prevent :my leerlinge around the f-iho'is rind to so adjust the peeking that it may, ii neeeeeery, he renewed wit-lmut Stopiiing or interfering; with the operation or the blower.

ln the ereoinpenying drawing, Figure i, Shows o horizontal seetional View through the end oi n rotary blower having my iinprovenent thereon. Fig. 2, is e eeetion on line XHX ot Fig. l.

The numeral I, represents the end easing oi the blower in which the inipeller allaite journeled. 2, 2, the iinpeller sheits.

3, 3, ere the gear wheels conveying the power from one iinpeller to the other.

4, d, are eollars surrounding the shaft-.e 2, 2. These Collars are secured in d stationery position and lieve their forward. ende finished smoothly, the roer portion being ser-ew threaded on the outside to nt an internally screw threaded gland or nut 5.

a, a, are Smell openings or holes in the gland 5, into which e Spanner een lie lit-ted when it is necessary to tighten or release the said gland.

6, 6, are rings of packing materiel surrounding the shafts end tting into the enennels or grooves 7, formed around the shafts and extending Sonie distance into the part forming the heed ofthe impeller.

S, S, are the circular heads of the iinpe-llers. These heads fit into the end of the outside easing of the blower and are mede to Conform to the pitch line of the geen' Wheels 3, 3, consequently, they just touch each other. Around the circumference of these eironlin' heads the leakage oeeurs when there is l the slightest book pressure developed on the inside ol' the 1nlower To fit the peeking around the Shaft, tlie Serew threaded gland 5, ,is turned heel-verd on the roller 4, thus leaving the inner und Smoothlifinished end of seidV coller exposed, the peeking is then iitted around this smooth end oi tire coller and the gland 5, Serewed up tightly, time loi-eine' the peeking into lelie groove 7, in the position shown in the drewving,r and :it the seine time holding` it Statline ary agonist rotation between Seid eollzu' el end the adjacent portion oi the easing, sind preventing any leakage around the shells.

The part oi' the end frame of the blower directif.T over the gland is lelt open or provided with a. movable cover, so that the peeking may lie renewed or adjusted Whom ever it is necessary to do Se.

Having thus described my invention what eleiin es new is:

i. ln e pump or blower, o, rotary sheft having in the part inside of the Aionrnel :15 eireuler groove. or channel adopted to receive a, peeking material, e stationery eoller fitting around said shaft and having its outer end externally screw threaded and en internallyv Soren threaded gland iittinflr around said eollar end adopted to force t ie packing nieterial in the eireuler groove and tightlybetween the end of Seid eoller and the adjacent portion of the easing, whereby the peeking will be held .in a Stationary position and the leek age from the pump or blower prevented, substantially es shown.

2. ln a. rotary blower, the combination et the shaft 2 hedging the annular packing groove 7, the externally screw threaded stetionary collar 4, ltting around the Seid shaft and the internelljirv screw threaded gland 5, tting over seid collar and the peeking 6, fitting around the forward end of the eoller 4, and into the annular groove 7, und held stetiene@y between seid collar und the :tdjeoent portion of the easing, substantially als shown end for the purpose described.

3. In a rotary pump or blower, the Colnbina-tion with e rotary shaft having in the fis parl'. tu tbe inner side el the jum'lml u. ein-.ul the end el said collar and tbc adjacent pur- 1o lul.' groove, el' :Ln externally serew-Lllrmuled tien el' the easing, whereby leakage from tbe Stationery eellau' en Huid shalt., :L peeking pump 0r blower will be prevented.
